TILTING TRAY.

Application-filed November 25, 1921. Serial No. 517,624.

This invention relates to tilting trays for use in holding, transferring and handling slabs or sheets oit wall board, plaster board or other material in the process of making,

finishing or otherwise disposing of the same,

and it has for its object tok provide means of the character stated which will be generally superior in relative simplicity and inexpensiveness of' construction, taken inconnection with durability, inherent strength,

convenience and facility in use and manipulation and operation, compactness in form and general efficiency and serviceability.

lVith the above and other objects in view,

the invention consists in the novel and useful provision. relative arrangement, combination, association and inter-relation and construction of parts, members and features, all as hereinafter described, shown in the drawings, and Finally pointed out in claims.

In the drawings:

Figure 1 is a side elevation of the tilting tray in its entiret 7; i

Figure 2 is a plan view of a ledgemember utilized in practicing the invention;

Figure 3 is a perspective view of upright members or supporting lmembers used for supporting the tray member;

Figure l is an end view of the member 130 shown in Figure 1 with the frame member .'15 or' a portion ot the frame member carrying arbois and a locking aim.

Corresponding parts in all the figur-es are designated by the same reference characters.

Referring with particular-ity to the draw- -zo ings, the improved tilting tray is designated in its entirety by A, oit' which 1 is a tray member, 2 supports between the tray member and a carriage member 3, all of which elements are used in practicing one embodii ment ot the invention. The carriage member 3 may include the usual spaced flanged wheels #l joined by an axle 5, which wheels are adapted to iide upon a track 6. Obviously the carriage member might be some so form oft' truck and the wheels 4 do not of necessity have to be flanged. Aframe member 'T is carried upon the axles 5, as shown in Figure s, and there is afront and rear carriage 3 between which an I beam 8 eX- tends, which I beam is supported upon the Jframe member l in each case and bolted or otherwise held to vsaid lrame members 7. The uprights 2 are supported upon the beam Si as shown in the figures, and said uprights are provid-ed with two depending spaced members 9 and 10, which straddle the beam S. A transverse plate 11 is adapted to rest on the top of the beam 8 and to be fastened thereto by means ot bolts 1Q. passing through perforations 18 in the uprights 2. The depending'members 9 and 10 are. likewise pro vided with aligned perforations 14 and a bolt is adapted to pass through said perforations and the perforations in the beam 8 to securely hold theV upright members to the beam as shown at 15. The supporting means comprise two pairs of supports 2, one pair being adjacent each end or' the tray member, and the supports of each pair being separatedeeach Vfrom the other, The supports are provided at one end with bear' ing grooves 16. rThe tray member 1 which includ-es a trame 17 .as well as the tray 18 proper, is somounted upon the uprights 2 that the trame with its tray may be tilted into position as illustrated in Figure 5. In particular the frame member comprises two spaced longitudinal members 19 and 20 with cross pieces 9.1 joining said members 19 and 20. There are two cross pieces 21 andthey vare received within the space between each pair olsupports 2. The cross pieces are shown in Figureyand it is to be observed that they'are channeled in order to give strength to said pieces. A strap member 22 is carried at an .intermediate portion ot 'the cross pieces and said strap member in turn carries arbors 23 and 2li. Said arbors are conveniently held to the strap 22 as by means of U-bolts ATo aid in preventing crushing ot the strap member 29. small supports 26 are interposed between the cross pieces 2l and the straps 22. The en'ds of said cross pieces are provided'with upstanding clips 27 and the members 19 and 2O are adapted to be received between said clips 27 and rest .upon a surface of the same, as best shown m Figure el. A base member 28 is joined to the members 19 and 20 and corner pieces 29 are provided between the membersv 19 and 28' and 2O and 28 lto give rigidity to the structure. Bolted to the member' 20 are upstandiiig members 30 and the edge rail 31 shown in Figure 2 is adapted to be slipped over said members 30 asfindicated in dotted Vline in Figure 1. Theedge rail comprises two spaced members 32 and 33 having-the usual spacer blocks 34 'and said edgerail operates in conjunction with the base 28 to prev-ent articles such as a wall board carried on said base from sliding Ytrein'saidbase when the frame is tipped into the position illustrated in Figure 5. `When the frame member considered as an entirety is placed upon the supports 2, tlie arbors '28 and 24 will be received within the bearing grooves 16, and 'as a consequence a pull upon one end of the trame willcause a tilting action ot the trame with respect to the carriage, as well as the uprights 2. iii-locking means is provided which is received in the space between eacli pair oi" supports 2. This locking means 235 includes an arm member pivotally joined to the members 2l asshown at 36, with a portion ot said locking means provided with a nose 3"( and with an angularly directed extremity7 38. Vhen the trame is in a horizontal position, as illustrated in Figure 4, the angular extremity of the loeliinO member 35 will engage an edge of the I beam 8,. A pull upon the arm 85 will `tilt the trame into theposition shown in Figure 5 so that the nose 37 may engage an edge of the I beam 8 as shown at 39. rllhe trame in its'tilting action will contact with the frame member 7 and limit 'further rotation or tilting of the traine. The wall board may then be easily removed :trom the tray, whereupon the locking arms 85 may be released and the ti'ameagain assume a hori- Zontal position as illustrated in Figure 4i. Quite obviously the lettdiand side of the trame 'migl'it be provided with an edge rail and further locking arms 35, so as to allow the trame to tilt to either side.

It is obvious that many changes and modifications maybe made in practicing the invention in departure fromv the particular showing, all, however, without' departing from the true spirit of the invention and the scope ot the appended claims Having thus disclosed my invention, I claim and desire to secure by Letters Patent:
